and combination of parts hereinafter described and subsequently claimed. Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this Similar characters refer to specification. similar parts in the several figures therein.

Figure 1 of the drawings is a view inside elevation showing my improved detachable horseshoe appliedto a horses hoof. Fig. 2 is a top plan view of the shoe with the clamping-mechanism closed. Fig. 3 is a similar view with the clamping-mechanism open. Fig. 4 is a plan view of one of the bail-members detached. Fig. 5 is a view in side elevation of the same. Fig. 6 is a vertical cross-section taken on the broken line 6-6 in Fig. 1, through one of the calks. Fi ..7 is a planview of the blank adapted to ie bent up to form the body of the shoe.

Fig. 8 is a side view of the stop-block and the pivot-pin upon which the same is eccentrically mounted. Fig. 9 is a plan view of the tread-plate detached. Fig. 10 is a bottom plan view of the toe-portion 0f the shoe, showing a preferred form of toe-calk.

Certain objects of the invention are to facilitate the attachment as well as the removal of the shoe; to securely hold the shoe in place upon the hoof; to prevent injurious pressure upon the hoof by the heel-portion of the attaching mechanism; and to securely yet removably attach a calk to the body of the shoe. d

Other objects will ap ear in connection with the following descrlption.

Referring to the drawin wherein the invention is shown in pre erred form, 1, represents the body of the shoe having a rigid.toe-'clip, 2, and smaller side-clips or lugs, 3, said clips being adapted to overhang the front portion of the hoof in use.

A pair of bail-members, 4, are pivotally mounted upon the heel-portion of the shoe by means of vertical pivot-s, 5, and are adapted to embrace and be clamped u on the hoof to secure the shoe thereto. he bail-members, 4, are preferably made of resilient sheet-metal, and each has a flat horizontal heel-portion, 4, adapted to rest flatly upon the heelof the shoe; and each bail-member i is bent to curved form and given a slightly more than half twist where-, I

by it is adapted to conform substantially to the surface of the hoof when the bail is directly upon and injuring the hoof. The

front end of each bail-member is offset or bent toform an attaching lug, 7, ap ertured to receive thescrew-bolt, 8, one of said apertures being screw-threaded to engage the screw-threads on saidjbolt.

The shoe is applied to the hoof with the bail-members, 4, separated, as shown in Fig.

3, the hoof being inserted beneath the overhanging clips, 2 and 3, and the bail-members are then brought together outside of the toeclip, 2, with their ends seated in the groove, 6, in the toe-clip, after which the bailmembers are drawn together by means of the bolt, 8, until the hoof is securely clamped, so that the shoe will be held securelythereupon.

I have shown a stop-block, 9, mounted upon the heel-portion of the shoe, and the heel-portion of each of the bail-members formed with a lug, 10, adapted to engage said stop-block to limit the rotative movement of the bail-member upon its pivot 5. The stop-block, 9, is so located in a shoe adapted for a particular horses hoof that it will be engaged by the lugs, 10, and prevent further pivotal movement of the bail-memadapt the size of theheel-portion of the attaching-mechanism nicely to the size of the heel-portion of the hoof, the resiliency of the bail-members permitting their front ends to be drawn together sufficiently to se' curely clamp the hoof as above explained. The stop-block, 9, may be mounted upon the heelportion of the shoe in any known manner, but is preferably removably mounted thereupon, whereby blocks of different sizes can be employed upon the same shoe. In the preferred form of my invent-ion I have shown the stop-block mounted eccentrically upon a pin, 11, adapted to engage a similarly threaded aperture in the heel of the shoe, the block being of polygonal form. The block can be thus rotatively adjusted to bring one or another of its sides into the path of the lugs, 10, on 'thebaihmembers, such adjustment being suflicient to provide for ordinary use, while the block can be entirely removed and replaced by one of different size if desired. i 1

I have shown the shoe provided with removable calks, 12, each having a screwthreaded shank, 13, adapted to engage a similarly threaded aperture in the body of the shoe, and each having a malleable flan e, 14, adapted to be bent over the edge of t e body of the shoe after the calk has been screwed to its seat to prevent the calk from working lose by a reverse or unscrewing movement. To facilitate thus locking the calk upon the shoe, the edge of the shoe may bechamfered or cut away opposite the calk, as shown in Fig. 6.

The body of the shoe is preferably made of malleablemetal, as rolled iron or steel,

and is stamped or cut from the sheet of metal in the form shown in Fig. 7, after which the blank so formed is bent up to the shape shown in Figs. 1, 2 and 3. The body of the shoe may, however, be formed in anyknown manner and of any desired material suitable for horeshoes.

When the body of the shoe is made of a comparatively soft metal, I. apply to the underside thereof a tread-plate, 15, of hard metal, as sheet-steel, to protect and relieve the soft metal body of the shoe from wear. This tread-plate is apertured to receive the sc'rewthreaded shanks, 13, of the calks, 12,

which serve to hold the tread-plate upon the body of the shoe.

The tread-plate as well as the calks can be renewed from time to time. To remove the calks it is necessary merely to bend back the upturned edge of the flange, 14, whereupon the calk can be unscrewed and removed.

The head of the clampingbolt, 8, is provided with any aperture, 17, adapted to receivea key, 18, to lock the bolt against rotation after the bail-members have been drawn tightly together.

In Figs. 1 and 10, I have shown a preferred form of toe-calk, 19, the projecting 1 portion of the same being of skeleton form and having cutting edges, 20, extending longitudinally of the shoe, and other out- .tlng edges, 21, extendlng transversely of the shoe at right angles to the cutting edges 20. The cutting'edges,.2 0, serve to prevent side slip, while the cutting edges, 21, afford a good purchase for the toe upon the road-bed. This toe-calk may be secured upon the body of the shoe by any suitable connecting mechanism, such as bolts or rivets, 22, said connections passing through the tread-plate, 15, if the tra-ed-plate is used.

The skeleton form of calk just. described is preferably secured to the body of the shoe by means of a plurality of connections whereby rotative displacement of the calk is rendered impossible thus insuring the retention of its cutting edges in the proper lines.

What I claim as new and desire to secure by Letters Patent is 1. A detachable horseshoe comprising in combination the shoe-body; a pair of bailmembers formed of resilient sheet-metal, each havinga heel-portion pivotally mount-- ed upon the heel of the shoe-body upon a Vertical axis, andhaving a lug on said heelportion, said bail-membersbeing adapted to embrace the hoof to which the shoe is atta'ched; a stop-block in the path of said lugs on the heel-portions of the bail-members whereby their rotative movement is limited; and means for securing together the front ends of said bail-members.

2. A detachable horseshoe comprising in combination the shoe-body; a pairof bailmembers formed of resilient sheet-metal, each having a heel-portion pivotally mounted upon the heel of the shoe-body upon a vertical axis, and having a lug on said heelportion, said bail-members being adapted to embrace the hoof to which the shoe is attached; a polygonal stop-block; a pin adjustably mounted in the heel-portion of the shoe-body, upon which pin said stop-block is eccentrically mounted in the path of said lugs upon the bailmembers whereby their rotative movement is limited; and means for securing together the front ends of said bailmembers.

3. In a detachable horseshoe, and in combination, a shoe-body having a toe-clip; a pair of bail-members formed of resilient sheet-metal, each having a heel-portion pivotally mounted upon the heel of the shoesaid lugs on the bail-members whereby their body upon a vertical axis, and having a rotative movement is limited. 10 lug on said heel-portion, and each bent to In testimony whereof, I have hereunto set curved form and having a twist whereby its my hand this 2nd day of January 1912.
